I'm at my "five device limit" in iTunes, and I'm getting a new Macbook Air. I sold one of my previously authorized devices, so I want to remove it from the list in iTunes, but I see the only choice I seem to have in iTunes app store is to deauthorize all my devices. Surely, after all these years, the geniuses at Apple have changed this in iTunes/App Store management to something more convenient, right? Right? So, where and what is the more convenient way to address this issue in iTunes/App store management?
